1969-1970

The Ford Mustang was restyled again in 1969: 4 headlights, 4 inches longer, and half an inch wider.  There were three new trim packages offered for the Boss, Mach 1, Grande, and GT, all performance models except for the Grande, which was intended as a sort of luxury Mustang.  There was also a special edition economy model with a 250 cubic inch six cylinder called the Mustang E, but they were very limited (50 units made).1969_Ford_Mustang_3.JPG

A wide variety of engines were offered in the different trim lines, such as the 302, 351, 390, 428, and 429. The horsepower of the various engines ranged from 220 horsepower to 376 horsepower in the Boss 429.  The 1969 Shelby Mustangs were back again, featuring similar high performance engines as the prior year along with exterior changes to set them apart from the GT's.  The Mustang Mach 1 was basically a higher performance Mustang GT with the addition of nicer interior and reflective stripes, a rear wing, side window louvers, and a shaker hood scoop.  The Mach 1 could be ordered with either the 302 Hi-Po, 351, or 428 Cobra Jet engine.  In some cases, the performance of the Mach 1 was not enough, and that was when the Boss Mustangs came into play.  The Boss Mustangs were offered in two forms, the first of which was the Boss 302, which was like the Mach 1 in that it was basically a high performance GT 302 equipped with exterior trim. The second of the Boss models is one of the most powerful factory Mustangs ever built in Ford history, the Boss 429.  This Mustang's 429 cubic inch engine was straight out of the NASCAR race teams, and was actually built by a third party customizing company for Ford Motor Company.  Only 867 Boss 429s were built, so getting your hands on one of these today will cost you quite a bit, much like it did back then.

The shocking news of 1970: the Mustang GT was no longer offered. The Mach 1, Grande, and Boss Mustangs returned and very little changed with their trim lines or with the Mustang as a whole.  Engine offerings were similar to those of 1969, with the exception of a new cylinder head design on the Boss 429's, a hemispherical head added in an effort to keep pace with Chrysler's 426 Hemi; with over 50 less horsepower than the Chrysler Hemi, it was a constant uphill battle for Ford.  There were however, 2 specially built Boss Mustang 429 Lawmen with around 1200 horsepower, built for tours of US armed servicemen. Never offered up for public sale, the last one in the world is owned by ex-NFL, ex-WWF member, and major car collector Bill Goldberg.  1970 also lacked a new Shelby Mustang model, so Ford re-titled the remaining 1969 Shelby's.
